Greetings fellow nerds. Today we’re going to use the silver nitrate made in a previous video to do a simple photography experiment. First you’ll need about one gram of silver nitrate and half a gram of table salt. Add enough water to both to completely dissolve them. Once they are both dissolved, add the salt solution to the silver nitrate solution. It will instantly form a dense precipitate of silver chloride. Give it a good shake to thoroughly mix the chemicals. Then let it stand for five minutes to settle down to the bottom. Then pour off the excess liquid. Now you have a solid powder of silver chloride. Get a piece of filter paper or paper towel and dump out the silver chloride onto it. Then carefully spread it out and pack it down into a thin but solid layer. Dry off the powder as much as you can with paper towel but don’t break up the silver chloride layer. Now let the silver chloride dry in a dark place. When it’s dry, take it out, and then place ontop of it, a template of something you want imprinted onto the silver chloride. Then place a sheet of glass over the template to hold it flat and steady. When you’re ready, shine a very strong light onto the silver chloride. Over the course of ten minutes, the silver chloride will decompose under the light to form a negative image of what was placed over it. Modern photography is much better and faster but this experiment shows you the basic idea. After ten minutes, remove the glass and the template. And now you have a negative photograph of the template. Pretty cool eh? Thanks for watching another NurdRage science video. Please Subscribe, Rate and Comment.
